After clearing Type Moon, start fighting for a better world

The time traveler, Xia Chuanhu
Young people with a physical age of 18 (?), a mental age of 30 (?), and an actual age of ???+
The Holy Swordsman of the Stars who inherited the Holy Sword from King Arthur, the Star Toucher who has a body with almost the same specifications as the True Ancestor's Princess Elquet, the Earth's UO candidate, the famous parallel world street urchin in the Clock Tower, and the super professional savior who has saved the world so many times that he has forgotten how many times!
After saving the world again, I have determined the following things from the bottom of my heart.
[Next time, even if Alaya and Gaia kneel down and beg me, I won’t save the world! ]
[I want a vacation! I want to retire! I want to retire! ]
[You want me to save the world? No way! ]
Then, only four years passed after my female brothers and sisters received the little books.
Xiachuan, I am not the old sword superman, the human form of Special Space Machine Arthur, Alaya, and Gaia’s designated big daddy, Tiger, have traveled through time again!
